Is crude oil a toxic substance?

    Yes, although the degree of toxicity varies from quite a lot to not much, depending on the composition. In the link go down to the section for “Types of Crude Oil according to the U. S. Environmental Protection Agency”.

    No matter the toxicity, oil, like non-toxic substances, can kill by smothering or by its volatiles displacing oxygen (or water, for aquatic life).
